Most often, cardiac arrest occurs due to arrhythmia, that is, due to such a change in the rhythm of the heart, for which the human condition is life-threatening. When the heart’s rhythm is disturbed, a defibrillator can send a dose of electrical current to the heart. As a result, the normal rhythm is restored.

If the shock delivered by the defibrillator is not strong enough, the rhythm may never return to normal.

In addition, we have often seen in movies how doctors resuscitate a person whose heart has stopped, with the help of a defibrillator. Now, that’s just a myth. The fact is that this device cannot affect the heart if it does not beat. That is, he can only return the rhythm to normal, but not the heart that is no longer beating.
